Referring to the drawings, particularly Figure 2, 20 designatesgenerally a ring twister, the frame of which is symmetrically arrangedso as to provide a machine having two similar sides 21, 21' (Figure 2)positioned back-to-back and with the spindles on one side in line withthe spindles on an opposite side and other parts thereof corresponding.As the sides are similar, only one will be described with similar partson the other side being indicated by a similar but primed number. Theframe of the machine includes generally vertically extending endportions, not shown, and a number of intermediate vertical supports oradjustable sampsons 22 (Figure 3) which may be equally spaced lengthwiseof the machine. Each sampson (see Figure 3) is made of a horizontallyextending spindle rail spreader 23 adjustably attached at the endportion thereof to vertical posts 24, 24 as at 25, 25'. These verticalposts may be of tubular stock, and at the upper end thereof there isadjustably attached in horizontal position a roller beam or upperspreader 26 as as 27, 27. The lower end of each post 24 has a footportion 28 which rests on the The spindle rail or lower spreader 23 isprovided at each end thereof with a mounting pad 30, 30' having slottedopenings 31 extending inwardly from one edge thereof. These pads providefor attaching to the sampson, the'spindle rail 32 which extendshorizontally between the said end supports. The spindle rail 32 ispreferably made of aluminum material extruded in a form so as to providea recess 33, a lip portion 34, a T slot 35 at the upper front edge ofthe rail, and a T slot 36 at the lower edge of the rail. The pad 30 isreceived in said recess and the lip 34 rests upon the upper edge of thespreader 23. Bolt fastenings 37 extend through suitable openings in thesaid spindle rail and project through the opening 31 to be engaged byjam nuts 38 so as to secure the spindle rail to said spreader 23. Thusthe spindle rail 32' is mounted to said spindle rail spreader 23 to beadjustably moved within the spreader along said post 24. p

The roller beam spreader 26 is provided with mounting pads 40, 40', eachhaving an'upstanding lip 41, 41' and a plurality of slotted openings 42,42 extending-inwardly from an edge thereof (see Figure 4). A roller beam43 preferably made of aluminum material is extruded in the form shown incross section so as to provide right angularly extending sides 44, 45and with the lower portion of the side 45 enlarged to provide a T-shapeslot 46 extending lengthwise of said beam. The roller beam 43 is alsosecured at its ends to the said end frame, not shown, and intermediatethe. ends thereof to said sampsons. The upper side 44 engages againstthe pad 40 in abutting relation with the lip 41 (Figure 10). Bolts 47extend through the side 44 and through the openings 42 to receive a jamnut 48 to securely clamp the said roller beams to the pad 40. Thus thebeam 43 is attached to the spreader 26 to be adjustably moved with thespreader on the posts 24', 24'.

The spindles indicated generally 51 (Figure 1) are mounted on thespindle rail 32 by means of individual brackets 52 (see Figures and 6)having a central opening 53 extending therethrough and through which theholster housing 54 (see Figure 2) of the spindle projects to bethreadedly engaged by a jam nut 55. The bracket 52 engages against theupper front portion of the spindle rail 32 and has spaced projections 56which slidably extend into the entrance opening of the T slot 35 so asto be properly located in position. Bolts 57 extend through suitableopenings 58 in the bracket and project therefrom to engage nuts 59aslidably received in the head of the T slot 35 to secure the bracket 52in adjusted position on the said spindle rail 32. Thus the spacing ofthe spin dles 51 may be readily adjusted lengthwise of the frame bymerely loosening the bolts 57 and sliding the bracket 52 along the rail32 to the desired location and thereafter retightening the saidbolts 57.

The ring rail 59 (see Figures 7, 11) is also preferably made of aluminummaterial extruded in a form generally L shaped in cross sectionproviding a leg portion 60 and an arm portion 61 projecting therefrom atan acute angle to the leg 60. The end of the arm portion 61 has a T slot62 therein extending lengthwise thereof. In mounting the ring rail onthe machine, the same is placed in the position shown with the armportion 61 projecting toward the spindle at a location inwardly thereof,which positions the T slot 62 to open on the underside of the said armportion 61 thereby protecting the slot from falling lint and the likelodging therein. The twister rings 63 (see Figure 11) are of a usualconstruction and each is supported in an individual holder 64 having aflange 65 provided with spaced openings 66 therethrough. The flange 65is positioned to engage the underside of the ring rail 59 as best seenin Figure 7, and bolts 67 having a head slidably received in said T slot62 project therefrom and through said openings 66 to be threadedlyengaged by jam nuts 68 to secure the said holder 65 in adjusted positionalong said ring rail whereby said ring 63 may be properly positioned inline with selected spindle 51.

The so-called thread board 70 (see Figures 10, 12') to which the threadguides 71 are attached is also made preferably of extruded aluminummaterial and has a T slot '72 opening on the underside thereof. Thethread board 70 is hingedly secured to the roller beam 43 as by means ofhinge blocks 73, best seen in perspective in Figure 12, whichblocks arealso made of extruded material of extended lengths and then severed to adesired length. Each block, of which there may be as many as is foundnecessary, has a T slot 74 opening on one side thereof and a ledge orstop abutment 75 on an opposite side. Each block '73 is securedto theroller beam 43 by means of a bolt fastening 76 (Figure having aheadthereon received in the said T slot 74 and with the shank thereofprojecting through a suitable opening in the roller beam 43 and engagedby a jam nut 77 which secures the said block in place. The thread board70 has a notch 78 cut therein to receive the block 73, the abutment 75extending inwardly of said notch and beneath the thread board so as toprovide a rest or abutment for said thread board to engage when in thehorizontal operative position thereof. A hinge pin 79 extends throughthe thread board and the said blocks 73 whereby said thread board may beswung to a vertical inoperative or horizontal operative position as theconditions may require. The thread guides 71 are of a usual type havinga thread guiding end portion 80 and pivotally mounted on individualbrackets 81 as at 82. Each bracket 81 is secured to the underside of thethread board 70, as best seen in Figure 10, by means of a fasteningscrew 83 which engages a nut 84 slidably received in the said T slot 72.Thus each thread guide is individually mounted in adjusted positionlengthwise of said thread board and may be individually swung to aninoperative position as indicated in dotted lines 85 or the thread boardas previously stated may be swung upwardly as indicated in dot and dashlines 86 to place all of the said thread guides 71 thereon out ofoperative position.

The front rolls indicated generally 90 (Figures 2 and 13) are supportedin a manner to provide adjustability thereof lengthwise of the machineand comprise a lower roller 91 which is supported in roller stands 92(see Figures 1, 2, and 13), there being as many of the stands 92 as willbe found necessary for the particular length of the machine. The stands92 may also be made of aluminum material extruded in extended lengths tobe thereafter severed into proper lengths for use. Each stand has a footportion 93 (Figure 13) provided with a T slot 94 and a depending lip 95.The foot portion 93 engages the upper side 44 of the roller beam 43 (seeFigure 13) and the lip 95 engages the side 45, which provides foraligning the stand in proper place on the said roller beam 43. A tiebolt 96, the head of which is slidably received in the T slot 94,projects therefrom through suitable openings in the side 44 to beengaged by a jam nut 97 to firmly secure the stand 92 in place. Theupper portion of the, stand has spaced recesses 98, 99 extendinginwardly from the upper edge of the stand. These openings are ofrectangular form, and the opening 98 provides a bearing in which isjournaled the said roller 91. The usual half-bearing block 100 may bepositioned between the bottom of the recess 98 and the bearing portion101 of the roller 91.

A cap bar 102 (see Figures 15 and 16) extends between pairs of adjoiningstands 92 and has its end portions reduced as at 103 to provide ashoulder 104 at either end thereof. The reduced portions 103 arereceived in the recess 99 of adjacent stands and there secured in placeas by means of screw fastenings 105, the said shoulder 104 preventingmovement longitudinally of the said cap bars 102. The cap bars 102provide supports on which are mounted a plurality of pairs of spacedbrackets 106, each having a foot portion 107 provided with an openingtherethrough of a size and rectangular shape corresponding to the crosssectional shape of the bar 102 to be slidably received thereon andadjustably secured thereto as by means of a fastening 108. The brackets106 extend upwardly from the cap bar 102, and the upper end portionthereof is provided with recesses 109, the walls of which extend in agenerally vertical direction. A pressure roller 110, one for eachspindle 51, is supported by pairs of said brackets 106 and is providedwith trunnions 111 (Figure 15) which are received in said recesses 109to be guided thereby toward and from the bottom roller 91 in a usualmanner common to drawing rollers of machines of this character.

The machine is also provided with the separators 112 (Figures 1 and 2)which are positioned substantially midway between adjacent spindles 51(see Figure 1). Each separator 112 is hung from a bracket 113 (seeFigure 10) having an upstanding flange 114 provided with an opening 115.The bracket engages the lower edge of the beam 43 and the flange 114engages the rear of the side 45 of the beam. A bolt 116, the head 117.of which is slidably received in the T slot 46 and the shank of thebolt extends therefrom to .be received in said opening 115 to projecttherethrough and is engaged by a jam nut 118 to adjustably secure saidbracket 113 in place.

Each separator has a vertical row of holes 112", any one of which can beengaged on the raised button 113" of the bracket 113 to secure the mostfavorable disposition of the separator 112. It is only necessary tospring or bow the separator inwardly at the location of the button 113to release it from the bracket and then the separator may be sprung backinto place to be secured on the cast button 113" by means of any one ofthe vertical holes. This adjustment is especially desirable when thevertical spacing between the roller beam and the spindle rail is to bevaried as when changing to another bobbin traverse.

As is usual in machines of this character, the spindles 51 thereof aredriven from a drive drum 119 (Figure 2) which has a shaft 120 rotated bya drive mechanism, not shown, and usually housed at the end of themachine, not shown. In the present instance the shaft 120 extendslengthwise of the machine and is supported intermediate its ends bymeans of a bracket 121 which is slotted at 122 for adjustablypositioning on the roller beam spreader 26 substantially midway thereofto depend therefrom and is secured thereto. The shaft 120 is journaledin the bracket 121 and is thus fixed relative to said roller beamspreader 26. from the drum 119'to the spindles on each side of themachine by means of an endless tape or belt 123 which is guided andtensioned by means of idler rollers 124, 124 journaled for free rotationin brackets 125, 125.

These brackets are pivotally mounted on rods 126, 126" which extendlengthwise of the machine and are supported intermediate the endsthereof on the spindle rail spreaders 23 of the machine. The arm 125 andopposite arm 125' are resiliently biased toward each other by means of apull spring 126, the'ends of which are secured in an appropriate mannerto the saidarms 125, 125'. It will be, of course, understood that thereis a pair of these rollers 124, 124 for each belt and that each belt isarranged to drive two adjoining spindles 51 on each side of the machine.

Although the roller beam spreader 26 is adjustable on the rods 24, 24,it is intended that this adjustment be only used for the initialpositioning of the spreader, as the vertical position of this spreadermust be such that the front rolls 9t), 90' line up exactly with the geardrives in the geared end of the frame. The slots 122 and the brackets121 are used to permitthe shaft 120 to be adjusted relative to the frontrolls and so as to align the shaft perfectly with the motor drive at theend of the frame and the gearing at the geared end of the frame. Oncethis proper spreader position is established it is not likely that itwould again be changed unless the entire machine is to be raised orlowered by adjusting all of the adjustable feet at the geared and footends and sampsons.

An important feature of this machine lies in its capacity to suit anyreasonable change in bobbin traverse through the raising or lowering ofthe spindle rail spreader 23 and spindle rail 32 relative to the rollerbeam spreader 26 and the roller beam in the above-mentioned fixedposition. In changing the machine from a given traverse to a longertraverse, for example, it is possible to lower' the spindle railspreader 23 at each sampson an appropriate amount to establish thespindle rails in a lower position. This lower position is necessary toaccommodate the longer bobbins on the same spindles with suitableballooning space between the upper head of the bobbin and the threadguides 71 and 71'. This same lowering requires that the rods 126 and 126and also the idlers 124 and 124' be lowered by the same amount, sincethe rods 126 are fixed to the spreader 123 and thus therewill bepreserved the same tape drive line horizontal to the spindles. The arms125 and 125 Motion is transmitted will swing outwardly-slightly tocompensate for the needed extension in perimeter of the tape 123 and thepull spring 126 will maintain tension in this new idler position. Thebuilder cross shaft 149, pivoted brackets 148, 148, and all other partsthat are suspended from the spindle rail would still operate properly intheir lowered position, and it is a simple matter to re-establish thedrive to the builder in the geared end to suit the lower position. i

In the present embodiment of the invention the ring rail 59 is fastenedto a bracket 127 (see Figures 2, 7, and 8) as by means of boltfastenings 128 extending through said bracket and the side 60 of thering rail. The bracket 127 is guided in its movement by means of a guiderod 130, the upper end of which is secured by means of a bracket 131having an opening 132 in which the upper end portion of the rod isreceived and therein secured by means of a fastening screw 133. Thebracket 131 engages against the lower edge of the roller beam 43 (seeFigure 13) at the rear thereof and is provided with spaced lip portions134 which extend to engage the lower edge of the said beam 43 and issecured as by means of fastening 135 which are slidably related in the Tslot 46. The guide rod 130 is additionally supported at a lower partthereof by means of a bracket 136 (see Figure 7) which is provided withan opening 137 through which the rod 130 passes and is secured to thebracket by means of a fastening 138. The bracket has a flange portion139 (see Figure 9) which extends beneath the spindle rail 32 to engagetherewith, and a T bolt 140 engages in the T slot 36 to projecttherefrom and through said flange 139 to be engaged by a jam nut 141 tosecure the said bracket 136 in place. The bracket to the bracket as bymeans of fastenings 143. This extension 142 is provided with alongitudinalopening 142a therethrough and through which the neck portion144 of the bracket 136 projects. The lower portion of the extension isprovided with a foot 145 through which an opening 146 extends forpassage of the rod 130 therethrough.

It will now be apparent that raising or lowering said extension 142 willin turn raise or lower the bracket 127 along the guide rod 130 andthereby traverse the ring rail 59.

The motion for traversing the ring rail 59 is provided by a usualbuilder motion, not shown, through which a rod 1 47 (Figures 1 and 2) isreciprocated axially lengthwise of the machine'in a usual manner. Thereis secured to the lower portion of the spindle rail 32 a plurality ofbrackets 148, one only on each side being shown but it being understoodthat a number of these are provided depending upon the length of themachine and in numbers corresponding to the number of lifter brackets127. There is journaled in the brackets 148 a shaft 149 on which ismounted a lever 150 extending generally upwardly therefrom intoengagement with a block 151 secured to the said rod 147. There is alsosecured on the shaft 149 (see Figure 1) a lever 152 having at the freeend thereof a roller 153 which extends into engagement with the footportion 145 of the extension 142. Thus, as the rod 147 is moved towardthe left as seen in Figure l, the shaft 149 will be rockedcounter-clockwise, thereby rocking the lever 152w swing the roller 153in an upward direction and thereby raise the ring rail 59 upwardly. Thereturn of the ring 59 to the lower position thereof is effected in ausual manner by gravity.

It is also contemplated that the supply package or creel supportingstructure may be so arranged that the supply package spindle 159 may beadjustable lengthwise of the machine in accordance with the position ofthe spindles. To this end a laterally extending bar 160 is fastened inan appropriate manner, not shown, to the roller beams 43 and is providedsubstantially midway thereof with an apertured boss 161 in which isreceived a standard 162 secured in place by means of a fastening 163.which may be a usual bolt. This standard 162 supports a bracket164.having two similar sides 165 and 165 on which is secured a creelrail 166. This rail 166 preferably is made of aluminum material extrudedin a form so as to provide a T slot 167 extending lengthwise thereof.The inner ends of the creel pins 159 are reduced as at 169 providingshoulders to receive thrust washers, and then threaded so as to engageinto nuts 168 slidably received in. the T slot 167. The creel pin isfurther provided with an opening 179 to receive the pin or like tool toturn the said creel pin into the nut 168.

It will now. be apparent that I have disclosed a textile machine inwhich the several rails may be advantageous ly made of extruded materialwith a slot to provide simple, inexpensive anchorages for tie boltsemployed for securing the associated elements of the machine in place.Slots formed by this extrusion do not require breaking of the skin ofthe extruded material such as by machining, which is known to weaken theextrusion and sometimes permit of warpage of the rail. It will also beapparent, that the rails made as above described provide a choice ofspindle spacing which may be readily changed without additionalmachining of parts and which rails provide an efficient means forsecuring horizontal alignment of spindles and associated elements.Theinvention also contemplates the use of the several parts as aids inregauging an existing machine of the above type. The term memberextending lengthwise of the machine is herein, employed to designate thehorizontal beams .or bars some of which are usually referred tospecifically as. creel rail, spindle rail, ring rail, thread board, androller beam.
